[mythtvnz] DVB-S no lock when scanning channels on 12483 but 12456 is ok.

[Julius Spencer]

Hi,

I have the same problem - have had for about a year now.  While scanning II have a signal of 98% and the signal/noise % bounces around and I don't get a lock.

I have even bought a second card in case the old one was broken - so now I have two Nova S Plus cards.

Did you manage to figure it out?
(I have a DSE Freeview device which can play all channels so I know it's not the dish or signal)

I am using:

Frequency : 12456000 or 12483000
Polarity : horizontal
Symbol Rate : 22500000
FEC : Auto
Inversion : Auto

Cheers,
Julius.
